McDaniel claims that a committee run by Henry Barbour is behind the ads, but a Mississippi radio station owner recently said that a Democratic operative contacted the station about running the ads.

In a Wednesday statement, McDaniel compared the Mississippi ads to tweets from a Democratic operative about McConnell's wife, Elaine Chao, about how she "isn’t from KY, she is Asian."

"The statement made by the Alison Grimes supporter is absolutely an offensive statement, and that type of behavior has no place in politics, period," McDaniel said in the statement. "Just as Senator McConnell was right to condemn such behavior in Kentucky, he should also condemn the race-baiting, incendiary language employed against Republicans and conservatives in Mississippi."
